Geforce GTX 670 vs Geforce GTX 760

Intro

The Geforce GTX 670 makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific model. It features 1344 SPUs along with 112 TAUs and 32 ROPs.

Compare all that to the Geforce GTX 760, which uses a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this particular model. It features 1152 SPUs along with 96 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x.
The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen.
The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
